BACKGROUND Personal hygiene often is temporarily sacrificed as a result of inconvenience and, to some extent, laziness of persons. Typical is the inconvenience of the student or of the wage-earner or businessman or business-woman who, being away from home either during the business day or during a brief business trip where it is not readily convenient nor practical to carry a separate tooth brush. On the other hand, practically every person during business hours needs a shirt-pocket retractable pen.

in the concept of encasing a tooth brush within a pen casing to thereby make a readily available and accessible tooth brush, many problems as well as practical factors become involved. For example, moisture or water from a wet tooth brush would tend to drain toward the writing end of a pen when the pen is. snapped'onto a shirt pocket or when the pen is being used for writing, whereby the moisture and/or water easily could foul the reserve ink of the pen refill shaft, and/or moisten the pen point such that the pen fails to write or such that the ink smears and/or fails to promptly dry, as well as the possibility that the ink because of the moisture or water would flow from the ink-reserve shaft toward the tooth brush to ruin the tooth brush and possibly soil the hand of the user, or flow through from the pen casing out of the casing to thereby stain the shirt or coat pocket of the person.

Also, during a brushing of teeth, there is a to-and-fro motion, and where the pen casing is the tooth-brush handle, there must be a lock or de-activating mechanism preventing accidental ejection of the pen point to avoid making the grasping hand of the person, as well as preventing the toothbrush shaft, from retracting and- /or axially shifting and/or rotating within the casing.

Because of the many possible complications typically of the type discussed above and what would appear to necessitate impractically complicated and costly structures rendering such a combination impractical from a commercial point of view, both cost-wise and from the standpoint of the resulting structure being probably too cumbersome, unwieldy, and the like, such a combination would not normally be built by the o'rdinaryartisan characteristic of normal businesses.

SUMMARY OF THE INVENTION Objects of this invention include a combination overcoming one or more ofthe above problems and achieving one or more advantages of the type discussed above.

Another object is to obtain a combination in which the mechanisms of the ejection and retraction of respectively the tooth brush and thewriting pen are functionally inter-related and dependent upon each other.

Another object is to obtain a'simplicity of design.

Another object is to 'make the mechanism and operation fool-proof against accidents insofar as ink reaching the tooth brush or moisture or water reaching the pen, the reserve, or the pocket in which it is clipped.

Another object is a toth'brush-writing pen combination of low cost of manufacture.

Another object is a structure for the combination which is compact.

Another object is the combination which will provide adequate handle and shaft for the tooth brush and yet will concurrently provide a small easy-writing pen when'the tooth brush is in the retracted enclosed state.

Another object is to provide alternative mechanisms of operation of the combination.

Other objects become apparent from the preceding and following disclosure.

One or more of the prededing objects are obtained by the combination of this invention as hereafter described.

Broadly the invention may be described as a toothbrush pen or pencil combination, in which the writing point is ejectable at one end of the pen casing and the tooth brush is extrudable and operative from the opposite end of the casing. More particularly, a common spring mechanism is biased within the casing such that it facilitates either ejection or retraction of each of the scriber means such as a pen or pencil, and the tooth brush. Also, the combination is soconstructed that ejection of thepen, for example, makes it impossible to effectively eject the tooth brush as a result of inactivating the mechanism and/or locking the tooth brush mechanism, also the ejection of the tooth brush makes it impossible for the pen to be ejected because of inactivation of the ejection mechanism of the pen or the activation of a locking device. The invention resides in both the conception and the designing of the practical embodiment of the conception, of the inter-related functions and mechanisms. Additionally however, the invention also resides in the particular inventive different embodiments, of which some embodiments have some advantages not included by the other embodiments. Also, for any one or more of the embodiments, there may be present or absent preferred embellishments and/or features which however on a commercial basis might not be as desireable for mass production becauseof possibly complexities and/or cost of manufacture. in addition to the features discussed above, a major feature of the invention is its convenient size for easily handling the pen when writing as well as the easy storage of the pen in a shirt or coat-brest pocket by the inclusion on the pen casing of a conventional or other desireable clip characteristic of any pen or pencil carried in a shirt or coat pocket.

The invention may be better understood by reference to the following figures.

THE FIGURES FIG. 1 is a cross-sectional side view of the tooth brush-pen combination. In this embodiment, the upper cap may be unscrewed, inverted, and rescrewed onto the lower casing in order for the tooth brush to be extending away from the casing, ready for use in the brushing of teeth. For operation of the pen, the pen point is ejected by merely downwardly pressing the buttonand maybe subsequently .be retracted by again repeating the pushing downwardly of the button.

FIG. 2 illustrates a second embodiment in which the cap may be removed and screwed onto the scribing end of the pm which has male threads mateable with the female threads within the cap, and upon the removal of the cap and spring mechanism of the pen causes the tooth brush head to be ejected above the opening in the casing so that it may be easily grasped by the fingers of the person and pulled outwardly to a point which at which it can then be turned such that the male threads on the lower end of the tooth brush shaft become mateable with the female threads in the upper end of the casing, thereby the tooth brush shaft being screwed into a locked position ready for the brushing of the teeth, utilizing the casing and screwed-on cap as a handle. The pen ejection and retraction mechanism is similar to that of FIG. 1. As is apparent, FIG. 2, similar to FIG. 1, is a side cross-sectional view.

FIG. 3a illustrates in part a prospective view of the annular activating cam having a plurality of small activating cams mounted around the outer annular periphery thereof.

FIG. 3b illustrates a partial view, taken as an elevation plan view of the inside lower wall of the lower casing of FIG. 2, illustrating typically the appearance of grooves in the wall for the upward and downward sliding action of the annular cams small peripheral cams, and the upward and downward and revolving to lock or unlock motion of the annular disk.

FIG. 4 illustrates an annular disc rotatable and depressible by depressing action of the annular cam of FIG. 3. 1

FIG. illustrates a cross-sectional view of the annular disk shown in FIG. 4.

FIG. 6 illustrates a novel but optional locking device serving at one end as a lock and at the other end as a lever for the lock as well as a pen or pencil pocket-clip for clipping the combination onto a shirt pocket. The view illustrated in FIG. 6 is a partial view of a crosssection taken along a plane parallel to a longitudinal axis of the tooth brush-pen, the view illustrating a wall of the lower casing, a screwed-on wall of the upper capcasing, a tooth brush shaft, and a locking lever device also utilizable as a clip for clipping the pen onto a pocket edge of a shirt or coat.

FIG. 7 is still a third basic embodiment, the spring mechanism of this embodiment serving to eject a pen, as contrasted to FIGS. 1 and 2 in which the spring serves to retract the pen, when a locking key is retracted to release the pen to be ejected to a writing position. The key is released by a downward pressure on the tooth brush shaft which in turn is pressed downwardly by any convenient mechanism such as the buttons such as illustrated in either of FIGS. 1 and 2. In order to retract the pen, the shaft of the tooth brush would again have to be pressed downwardly to remove the key from the locking slot of the pen in the ejected and concurrently the pen point would have to be pressed upwardly by pressing the pen casing downwardly against a firm or hard surface.

FIG. 8a illustrates an optional novel mechanism for locking the tooth brush shaft into a position suitable to withstand the to-and-fro movement of brushing the teeth, the view of FIG. 8 representing a partial view, taken as an elevation plan view, of the inside wall of the lower casing, disclosing the groove in the wall in which a key extending from a tooth brush shaft is ridable upwardly to a predetermined point at which the tooth brush shaft may be twisted to a locked position where it remains during the tooth brush operation. FIG. side cross-section has a container.

FIG. 81; illustrates a partial view taken in crosssection of a tooth brush shaft having a key extending therefrom rideable in the slotof FIG. 8a.

FIG. 9 illustrates still a fourth major basic embodiment of the invention, in which the depressible cam and the rotatable disk are mounted in the cap-cover casing, similar to conventional ejection and retraction pens, but in which the cap may be unscrewed from the tooth brush-encasing position and may be screwed onto the scribing end of the lower casing which has male threads onto which the cap may be screwed, and in this very simplified embodiment upon removal of the cap, the downward pressure of the screwed-on cap casing is relieved whereby the tooth-brush is ejected at least partially upwardly where it may be grasped by the fingers and pulled to a point at which by twisting it the male screw threads thereof become mated with the female threads on the inner upper casing which are similarly illustrated for the FIG. 2 embodiment.

FIG. 10 illustrates a partial view of a modified form of the invention in side cross-sectional view, in which there is provided additionally an inserted casing of tooth powder or paste.

DETAILED DESCRIPTION OF THE INVENTION FIG. 1 discloses an upper casing I screwed onto a lower casing 2 having female threads 3 mateable with male threads 4 of the lower casing. The upper casing 1 a through passage 5 sufficiently large in diameter to receive button 6 mounted by a threaded screw 7 screwed into the tooth brush shaft 8 extending through a narrowed portion 9 of the through passage 5 which thereafter enlarges to a diameter greater than the tooth brush head 10 and to about the diameter of the female threads within the upper cam cover. The enlarging of the shaft from the channel 9 in movement downwardly toward the threads define the abutement 11 which serves as a shoulder preventing upwardly ejection of the tooth brush head through the channel 9. The inner upper walls of the upper walls of the channel 5 include female threads 12 mateable with the male threads 3 of the lower casing. Extending from the tooth brush head 10 are the tooth brush bristles 13, the annular ring 14. Also preferably also includes helical threads screwable downwardly on the male threads 3, and extending from the ring 14 is the pocket 15. Within the side wall of the casing 2 are grooves corresponding in number to the small (minute) cams(of the annular cam 17) 16 downwardly pressable against the annular disk 20 having key 18 downwardly rideable in deeper grooves 21, alternate grooves 21a and 21b serving as alternate nonlocking and locking grooves for retraction and ejection pen positions respectively. The diameter of the cupshaped cam (annular cam) 17 is such that the outer wall is loosly slideable upwardly and downwardly within the lower casing 2. The pen 23 housed within the cup-shaped cam 17 includes abutment (annular) 24. Spring 25 is biased between the annular abutment 24 and ridge 26. The ridge 26 prevents any moisture-or water from draining down into the space of pen channel 29 from the collection space 28. The lower casing includes separately removable end portion 30 having male portion 31 screwable into female threads 32 of easing 2.

FIG. 2 illustrates a different embodiment in which the tooth brush shaft 8c is continuous with the cupshaped annular cam 170, such that upon removal of the cap-casing la the spring 250 presses upwardly against abutment 24a which in turn presses against the annular disk 200 which presses upwardly against the cupshaped annular cam 17a which causes the tooth brush head a to be pressed upwardly against the base of the button shaft 8b continuous with the button shaft 8a of button 6a having at 6b such that it is depressible into the channel 5a when pressure on the top of the button 60 presses the disk 20a downwardly causing it to rotate into a position which when pressure is relieved from the button 60 the disk 20a becomes locked in the downposition holding the pen 23a in the depressed position by virtue of the disk 20a acting downwardly on the abutment 24a. It should be noted that the groove 19a extends longitudinally through the helical female threads 23 such that the upper 18a may be slid through the grooves, whereby the male threads 35 may be brought into contact with the female thread 33 into which they may be mateably locked by a twisting screw action.

The FIG. 3a illustrates a partial view of the lower half of the cup-shaped annular cam 17 with the miniature cams l6 and their downwardly extending teeth 160.

FIG. 3b illustrates the grooves on the inside lower casing lower walls in which the miniature cams l6 and the annular disk 20 sliceably function, as previously described above.

FIG. 4 illustrates the annular disk with its upwardly extending teeth, as well as the alternate radially extending keys 37 separated by the intermittant recesses 36.

FIG. 5 illustrates in cross-sectional view the disk disclosed in FIG. 4.

FIG. 6 illustrates an alternate embodiment, in partial view, taken in cross-section along a plane extending through the pen along the pen's longitudinal axis, disclosing a lock 39 held in the locked position by the screwed-on cap-cover 10 having threads 4a mated with the lower casing threads 3a when the cap-cover is screwed on, with the lock 39 being locked upon abutment 40 of the tooth brush shaft 100 when the tooth brush is closed within the lower casing, and the lock 39 being slideable into the indentation 41 having abutment 41a when the tooth brush is permitted to be ejected to its extended position, the ejection being made possible by downward pressure on the lever 42 of the clip 43 pivotably biased on axis 44 of a ring 45 extending annularly around the lower casing. The shaft 10c includes also a shoulder 41b which prevents the tooth brush from moving in the downward direction also when to-and-fro tooth brush action of the grasping hand ordinarily would cause the shaft to shift within the casing. This is in contrast to the graded slope 46 which is essential for the defining of space 47 through which the key 39 will slip upwardly when the button in the upper casing is pressed downwardly to press respectively downwardly the tooth brush shaft 100 to move the shaft in a downwardly direction inorder to eject the pen or to retract the pen. The lower casing 2b includes perforations 27b.

FIG. 7 is a partial view takeniin side cross-sectional view of a third embodiment of the invention in which the pen 23b is biased downwardly by the :spring ZSbb acting against the shoulder 48 of the vpen and .at the spring opposite end 2Sc-acting against the upper wall 49 of the cup-shaped hollow pen shaft 17b continuous with the shaft 8d of the tooth brush (not illustrated). The lower casing 20 of this embodiment includes the bottom portion 2d of the lower casing as a continuation of the side portions of the casing 2c, it not being necessary to screw in a separate portion such as 30 and 30a,

in view of the fact that the FIG. 7 embodiment does not require parts of the mechanism to be inserted from the base of the pen. The pen point 23bb is ejectable from the aperture by relief of the locking key 51 acting against shoulder 52, the release of the key 51 being achieved by downward movement of cup-shaped shaft 17b base portion l7bb against the lever 51a whereby the key 51 is withdrawn radially outwardly permitting the pen 23b to move towards the aperture 50 50 whereby the pen point 23bb becomes ejected to a writing position and whereby the key 51 becomes locked into the annular grove 53 such that the downward pressure in writing does not press the pen 23b upwardly into the case 20. The pen 23b may be retracted by pressing downward on the tooth brush shaft 8d such that the base l7bb again presses against the lever 51a and concurrently the pen must be pressed downwardly against a hard surface to press upwardly against the pen point 50 in order to move the pen back up in the casing to a position such that the key 51 again becomes locked under the shoulder 52. This embodiment of FIG. 7 may typically employ a button such as button 6a of FIG. 2. The lever 51a typically extends from a ring 54 insertable from the top of the casing down into the base of the casing 2c.

FIG. 8a illustrates a partial view of an alternative tooth brush shaft locking mechanism in the extended position whereby a key 55 rides in a groove 56 on the inside wall 57 of a lower casing upwardly to the upper extreme at which point the shaft of the tooth brush may be twisted into either locing position 58a or 58b and whenever twisted into 58b may be further forced past a narrowed point into the continuing channel 66a leading upwardly for withdrawal of the shaft from the lower casing when desired.

FIG. 8b illustrates a partial view of a tooth brush shaft having extending therefrom a key 55 such as would be rideable in slot 56 of FIG. 80.

FIG. 9 illustrates a fourth overall embodiment of the novel inventive pen of this invention. This particular embodiment has a great utility due to its overall simplicity and low cost of manufacture. The casing 2d has screwed on the upper portion thereof a cap cover 1d having threads 3b screwed on male threads 4b. The cap 1d includes the retraction and ejection mechanism i.e. the rotatable disk 20b and miniature cams 16b, the cams being mounted on the shaft of button 6b depressible into cavity 5b. The cavity 34c has inclosed within it the tooth brush head and the shaft 8g with the male shaft 8g with the male threads 350 on the hollow cup-shaped base 17b.

Similar to the embodiment of FIG. 7, this embodiment also has an integral bottom portion 2e continuous with the casing 2d and preferably also having the isolation ridge and abutment 26b against which spring 25c is'biased at one end and biased at the other end against abutment (of the pen) 24b. Upper inter-casing 1d female threads 19b are mateable with male threads 35a, when the tooth brush is ejected to a point that the oposing threads may be screwed together.

.Each of FIGS. 2 and 9 embodiments may also preferably have a spring 25aa in FIG. 2 and 2500 in FIG. 9. The FIG. 9 lower casing 2d (illustrated) or upper casing (not illustrated) may have the clasp or its equivalent which may be anchored through the casing by the key 15b or any other suitable or conventional means of attachment.

FIG. 10 illustrates a partial view of a modified form of any one or more of the embodiments of the invention, in which there is an additional length of pen and- /or reduced brush-length portion allowing space for the insertion of a small container 59 of tooth paste or tooth powder or the like, with cap 60. Also there may be a narrowed cup-shaped casing 17d with an enlargement 61 for the snapping-in of an enlargement 62 on the pen shaft 230 whereby the pen shaft is not free to shakearound when the tooth brush is in the extended operative position for tooth brushing. Also as illustrated, for any one or more embodiments the button for ejecting the pen and retracting the pen may be a hollow shaft with the top of the button being a screw-on. cap for tooth powder, or mouth wash, or tooth paste, for example; if for tooth paste, it may include a conventional applicator stick attached to a conventional applicatorstick cap in the place of the cap 6c screwed onto container 63 with contents 64.

lt is to be understood that the size and shape of the various elements making up the combination of this invention may vary considerably as may be desired, and that there may be adult sizes as children sizes, for example. Similarly, it is within the scope of this invention to make various modifications(s) and substitution(s) of equivalent(s) as would be obvious to a person of ordinary skill in this particular art. Typical, for example, is the employment of a tooth brush shaft which telescopes from a collapsed state within the lower or ipper casing(s) to an extended rigid state, optionally also including a twist-locking mechanism, for example, which would prevent any tendency to collapse during the brushing.

The plurality of apertures such as 27 of FIG. 1, 27a of FIG. 2, 27b of FIG. 6, and 27c of FIG. 7, and also shown but not labeled in FIG. 9, provide for ventilation and moisture evaporation which might remain on the tooth brush or otherwise drain from the brush into the casing.
